Kent Overstreet, the creator of bcachefs, helps us understand where his new filesystem fits, what it's like to upstream a new filesystem, and how they've solved the RAID write hole.

  • bcachefs — bcachefs is an advanced new filesystem for Linux, with an emphasis on reliability and robustness and the complete set of features one would expect from a modern filesystem.
  • bcachefs Erasure coding — Bcachefs takes advantage of the fact that it is already a copy-on-write filesystem. If we're designing our filesystem to avoid update-in-place, why would we do update-in-place in our RAID implementation?
  • bcachefs Caching — bcachefs can be configured for writethrough, writeback, and writearound caching, as well as other more specialized setups.
  • bachefs Compression — Unlike other filesystems that typically do compression at the block level, bcachefs does compression at the extent level - variable size chunks, up to (by default) 128k.
  • bcachefs Encryption — bcachefs uses AEAD style encryption (ChaCha20/Poly1305), where each encrypted block is authenticated with a MAC, with a chain of trust up to root (the superblock), and every encrypted block has a unique nonce.
  • bcachefs Snapshots — bcachefs provides Btrfs style writeable snapshots, at subvolume granularity.
  • (2015) [ANNOUNCE] bcachefs - a general purpose COW filesystem — It's taken a long time to get to this point - longer than I would have guessed if you'd asked me back when we first started talking about it - but I'm pretty damn proud of where it's at now.
